We performed optical spectroscopic observation of Nova Sgr 2009 #3 (CBET 1899) on 07 Aug using KANATA/High Speed Spectrograph. The spectrum is shown in the figure. The H-a emission line showed an asymmetric profile. The FWHM of the Ha emission line was about 2100 km/s. The FeII emission and possible NaD absorption lines were seen.
